possible but oopses also occured on the other machine, although
they weren't logged, but okay I'll run a memtest.    And the filesystems
of these machines are synced via rsync, not via drbd, so the inodes
are different.

yes, they are mounted with acl, but it is not used at the moment,
I don't even think there is any file with acls set.
